I'm posting this on behalf of my mate Anna. She has a 12" Superdrive Powerbook. it was working last night but when she brought it to a lecture it wouldn't boot up. -we put it into firewire drive mode, all the files could be seen. -ran disk utility on it - no problems -we reset the power management and the Mac technician (on a side note; the only tech in our building. Macs dont usually need many technicians unlike the PC part of the building. my god they have an army) did a load of things but couldn't get it back on. Shes taking it into an Apple store tomorrow. does it sound like her computer is busted? My educated guess is that her memory is fried. it gets to the Apple logo+spinny circle thing and just doesn't progress. Any rev D superdrive PowerBook users experience anything similar?
